It is not our goal to “help Windows users” by making text editing on Windows more convenient. We aim to replace proprietary software, not to enhance it. So why support GNU Emacs on Windows?
We hope that the experience of using GNU Emacs on Windows will give programmers a taste of freedom, and that this will later inspire them to move to a free operating system such as GNU/Linux. That is the main valid reason to support free applications on nonfree operating systems.
